The group called Shadow Brokers claimed to possess and put up for auction NSA materials that affected Cisco’s PIX and Adaptive Security Appliance (ASA) firewalls and Fortinet’s Fortigate firewalls.

Cisco classified the Simple Network Management Protocol (SNMP) code breach as high vulnerability because it could allow an unauthenticated, remote attacker to cause a reload of the system or to execute code.

“An attacker could exploit this vulnerability by sending crafted SNMP packets to the affected system,” the advisory said. “An exploit could allow the attacker to execute arbitrary code and obtain full control of the system or to cause a reload of the affected system. The attacker must know the SNMP community string to exploit this vulnerability.”
